Answer:
E) Either anaphase I or II
Explanation:
Failure of segregation of homologous chromosomes during anaphase I or failure of segregation of sister chromatids during anaphase II leads to the presence of the abnormal number of chromosomes in resultant gametes. In the given example, the egg mother cell with 48 chromosomes (24 pairs) would enter meiosis I but the failure of one pair of homologous chromosomes to segregate from each other followed by normal meiosis II would result in the formation of two gametes with one extra chromosome and two gametes with one less chromosome.
On the other hand, if the nondisjunction occurs at anaphase II of meiosis II, two normal gametes, one gamete with one extra chromosome and one gamete with one less chromosome will be formed. Therefore, nondisjunction at anaphase I or anaphase II would have resulted in the production of eggs with one extra chromosome.
Answer:
Archaea domain is closer to eukarya than bacteria because genetically they are more similar to Eukarya than Bacteria.
Explanation:
Options for this question are:
- <em>They both lack a nucleus and contain cytoplasm.
</em>
- <em>The unique functional adaptations of Archaea are more similar to Eukarya adaptations. </em>
- <em>
They both evolved in the same geological time period.
</em>
- <em>
</em><em>Genetically, the Archaea are more similar to Eukarya than Bacteria.
</em>
- <em>
They both have membrane-bound organelles.
</em>
- <em>
Archaea is not closer to Eukarya because it contains prokaryotic cells just like Bacteria.</em>
Archaea are unicellular prokaryotic organisms, which share many characteristics with bacteria, however, the existence of metabolic functions and genes similar to eukaryotic organisms suggest that there is a genetic link between the two. Even the enzymes responsible for genetic processing, such as transcriptases and translation enzymes, are similar to those in eukaryotic cells.
The theory that establishes the relationship between Archaea and Eukaryotic suggests the existence of a common ancestor, whose later evolution allowed an Archaea to join a protobacteria to form a eukaryotic cell, and hence their genetic relationship.
